Title: Water quality meter
Inventor: KAWAMOTO KOTARO
IPC: G01N33/18
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a water quality meter which prevents the saturation of a sensor for measuring the concentration of substances by a method wherein the measured value of the sensor for measuring the concentration of substances is detected that it becomes close to an upper-limit value, a sensor output is adjusted automatically until it becomes a proper level and dilution water is poured. SOLUTION: Water A to be measured flows into a sensor 2 for measuring the concentration of substances from an inflow pipe 1, and it is drained from a drainage pipe 3 as drainage water B. The sensor 2 for measuring the concentration of substances measures the passing water A to be measured, and it outputs the electric signal of a sensor output S0 as a measured value. A control and computing part 5 outputs a control signal S1 until the measured value of the sensor 2 for measuring the concentration of substances becomes close to an upper-limit value, and it outputs the sensor output S0 as a measured-value output S2 as a measured value.  In addition, the control and computing part 5 controls an automatic flow regulating valve 4 in such a way that zero water C is poured until the sensor output S0 becomes a proper level when the measured value of the sensor 2 for measuring the concentration of substances becomes close to the upper-limit value, it corrects the sensor output S0 on the basis of a dilution ratio which is found on the basis of the water A, to be measured, per unit time and on the basis of the flow rate of the zero water C so as to be output as the measured-value output S2 .

Title: Process controller
Inventor: OTANI TETSUYA
IPC: G05B11/42
Filed: 1986-04-07
Abstract: PURPOSE:To reduce the overshoot by using a compensator which receives a limiter output, a controller output and the process response output and integrates the difference between a virtual process response when there is no limiter and a process output with the integration gain of the controller and then subtracting the compensator output from the controller output. CONSTITUTION:A sampler 1 receives a set value (yd) to perform sampling and supplies this sampling result to a subtractor 11. The output of the subtractor 11 is supplied to a PID controller 2. An adder 10 uses the output of the controller 2 as one of its own inputs. The output of the adder 10 is applied to a limiter 3. The output of the limiter 3 is applied to a sampler 4 with the output of the sampler 4 applied to a zero-order holding circuit 5 which is connected to a process 6. In addition, a sampler 7, a sampler 8 and a compensator 9 are provided. The compensator 9 calculates a virtual process response yiT through linear approximation from a calculated control input ui-1, an actual control input ui-1' and a process response (yi). The output ucn of said calculation is added to the output of the controller 2 by an adder 10 for correcting control input error. As a result, the overshoot is reduced as an actual process response (y).

Title: Control system interrupting device
Inventor: NAKAMU EIJI
IPC: G08B21/00
Filed: 1988-03-31
Abstract: PURPOSE:To operate the function of a fail-safe by making the cutoff contact of the driving circuit of equipment to be controlled with an AC signal generated when the difference between a real signal and a model signal is small, and converting the AC signal into a DC signal and breaking the cutoff contact in case of abnormality. CONSTITUTION:When the difference between the real signal S3 and model signal S4 is larger than a specific value, the integrating means 72 of a difference signal converting means is saturated and outputs a specific-value DC signal and when the control system interrupting device itself becomes faulty, its output is zero or the specific AC signal is not outputted even if the output is not zero. While the difference between the real signal S3 and model signal S4 is less than the specific value, the output signal of a difference signal converting means is maintained in the form of the AC signal and only while this AC signal is generated, a driving means inactivating means 2 disables the operation of the equipment 5 by the driving means 4 to be controlled unless an AC signal which for enabling the operation of the equipment 5 to be controlled by a driving means 4 is generated. Consequently, if a fault is present anywhere in the control system interrupting device 6, the equipment to be controlled is not driven and the function of the fail-safe operates.
